My pistol club bought a bunch of Crosman 2300T air pistols to teach
kids how to shoot. The triggers are heavy & generally atrocious.
Even with the trigger weight screws set to the minimum, most of them
are over the maximum weight Crosman says to expect. Many of them
started out over 4 pounds, which is ridiculous for 10 year old kids.
Competition air pistol triggers should be just over 500 grams.

As soon as the current pistol class is over, I have volunteered to try
to fix the triggers as best I can. There are YouTube videos on the
process, and basically you just polish up the stamped steel sheet
metal parts where they rub. There are aftermarket triggers with
rollers, but the club isn't going to pour more money into these
pistols.

I'm hoping the right lube will help maintain the trigger jobs for more
than a few shots. I don't think the surfaces are hardened beyond
whatever work hardening they get from stamping.

Any favorite lubes I shoudol consider? I have moly assembly grease
with a very high moly content, but I don't know if the PTFE stuff
might be better.

Thanks!

The surface finish is more critical than the lube you choose . And be damn
careful to maintain squareness and angles of contact . A surface that's in
full contact will have a lower per-unit pressure and feel lighter . Just
about any good quality gun oil will work just fine . IMO the moly-based
lubes are over-rated for most uses - they do have their place , and I like
'em in my wheel bearings .

Very well stated.

The normal method for most guys is to give em a lick and a promise
with a Dremal tool. And for a guy who has good control and knows his
techniques well..works fine. I personally set up triggers and sears
on a small industrial 12k rpm drill press and put my wheels in the
drill chuck..then use a raised flat block to lay my parts on and work
with the part absolutely flat..in good lighting, while wearing a
magnifying hood.

Also use a series of India stones, with the block as a guide to keep
things parallel and flat

Its little things like that that get one good triggers and not worry
about how long its going to take before they break in.

I was once told by a “gun safety” advocate back in the Nineties
that he favored total civilian firearms confiscation.
Only the military and police should have weapons he averred and what did I think about that?

I began to give him a reasoned answer and he
cut me off with an abrupt, “Give me the short answer.”

I thought for a moment and said, “If you try to take our firearms we will kill you.”"
